NO NO NO NO LOCALIZED OPERATIONAL EMISSIONS The proposed Project is to consist of the reuse of an existing 57,705 SF industrial building on a 4.99- acre lot as a soccer training facility. According to SCAQMD LST methodology, LSTs would apply to the operational phase of a proposed project, if the project includes stationary sources, or attracts mobile sources that may spend long periods queuing and idling at the site (e.g., transfer facilities and warehouse buildings). The proposed project does not include such uses, and thus, due to the lack of signiffcant stationary source emissions, no LST analysis is needed for operations. PROJECT GREENHOUSE GAS IMPACTS A numerical threshold for determining the signiffcance of GHG emissions in the South Coast Air Basin (SCAB) has not been established by the SCAQMD for Projects where it is not the lead agency. As an interim threshold based on guidance provided in the California Air Pollution Control Officers Association (CAPCOA) CEQA and Climate Change handbook, the City has opted to use a non-zero threshold approach based on Approach 2 of the handbook. Threshold 2.5 (Unit-Based Thresholds Based on Market Capture) establishes a numerical threshold based on capture of approximately 90% of emissions from future development. The latest threshold developed by SCAQMD using this method is 3,000 MTCO2e/yr for all projects (51). The estimated GHG emissions for Project land use are summarized in Table 8. The estimated GHG emissions include emissions from Carbon Dioxide (CO2), Methane (CH4), Nitrous Oxide (N2O), and Refrigerants (R). As shown in Table 8, the Project would generate a total of approximately 2,018.80 MTCO2e/yr. As such, the Project would not exceed the SCAQMD’s numeric threshold of 3,000 MTCO2e/yr if it were applied. Thus, the Project would not have the potential to result in a cumulatively considerable impact with respect to GHG emissions. Detailed construction and operation model outputs are presented in Appendix 1.
